- 摘要：
To provide a mechanism capable of highly efficiently acquiring low frequency components, or the object of an evaluation and from an output signal of a sensor.
SOLUTION: ADC 12 outputs digital signals formed by sampling an acceleration detected by an acceleration sensor 11 at a predetermined sampling frequency. HPF 14 attenuates components with a certain frequency or less specified by a cutoff frequency control section 17, from the digital signals. The cutoff frequency control section 17 defines the cutoff frequency of the HPF 14 to that equivalent to 10 Hz while a subject stands still to be ready to an address and defines the cutoff frequency to that equivalent to 1 Hz when the subject swings a driver.
